T1 Energy wins approval to turn Norwegian solar site into data center

T1 Energy, the US solar manufacturer formerly known as Freyr Battery, won approval on Thursday from the Mo i Rana municipal government to convert part of its Giga Arctic campus in northern Norway into a 50MW data center. Data Center Dynamics reported that the municipality rezoned 161,000 sq ft of the 926,000 sq ft site for industrial use or data center operations, with the rest of the campus remaining zoned for industrial development, subject to change once more grid capacity is allocated.

The approval turns a building planned for solar and battery storage into infrastructure for servers. T1 says the data center could be live as early as next year, that the existing building has room for a facility of that size, and that the company holds a place in the local grid queue for 396MW of capacity. The company also has a 50-year lease at the site, with an option to extend, and points to northern Norway's hydropower assets as a source of low-cost energy.

The campus has already lived one corporate life. It was first announced in 2022, when the company operated under the Freyr Battery name and the plan was a battery factory. T1 dropped that plan after it renamed itself in 2025 and shifted focus to domestic US solar manufacturing. A data center would be the company's first, according to T1.

At 50MW, this is not a hyperscale build. It is a first phase, and T1 has said the project carries expansion potential. The number that matters more is 396 — the megawatts T1 says it holds in the local grid capacity queue. The rezoned parcel covers less than a fifth of the campus by area; the rest of the land stays industrial unless and until more grid capacity is allocated. The land is waiting on the grid, not the other way around.

T1's own language makes the asset plain. "The people of Mo i Rana, Norway, today took a step towards the future and showed leadership in a future of AI and technology abundance with the approval of T1 Energy's plan to convert Giga Arctic into a world-class data center," chairman and CEO Dan Barcelo said, according to Data Center Dynamics. "We are in active discussions with multiple counterparties to find a strategy to unlock shareholder value."

That is the language of a company selling an option, not a factory. The site's manufacturing purpose has been overtaken by the data center plan; the value now sits in a queue position that is scarce and increasingly sought. The approval gives T1 something concrete to negotiate with — a permitted site in an industrial park with a long lease and hydropower behind it.

The campus has been announced as a battery plant, then a solar manufacturing site, and now a data center. The constant across all three is the grid connection. T1's history shows that industrial labels are provisional; the connection agreement is the durable part.

No client, lease, or capital partner is named in the coverage. What is known is that T1 is in active discussions with multiple counterparties, and Barcelo's reference to 'unlock shareholder value' suggests the company is keeping structure options open — a lease, a colocation venture, or a sale. What T1 has secured is the necessary condition: permission.

As this publication has argued, grid position is becoming the deal currency of digital infrastructure, and T1's approval is a compact test of that view. The factory was the vehicle that carried the option; the grid connection is the option itself. T1 is not selling solar modules or batteries; it is selling a conversion path from an industrial shell to a lit data center.

The permitting decision also offers a lesson for the wider buildout. The obstacle that dominates data center headlines is often the interconnection queue, not the zoning hearing. In Mo i Rana, the zoning hearing is done, the lease is long, and the queue position is the thing to watch. T1's next disclosure — a named counterparty for the first phase — will tell the market whether that queue position can be turned into a contract.

The first 50MW is the proof of concept. It could come online as early as next year, which would make the site a working reference point for the rest of the queue. What T1 does with the remaining 396MW will determine whether this is a one-off conversion or a template for industrial campuses sitting on undervalued grid connections.
